They work  and build without any problems in Ethereal (version 0.99.0) but when I try to separate and build them in Wireshark I have a lot of linking (unresolved symbol) problems. It seems like that functions/data structures in ethereal files (and needed and included by the dissectors) have been removed or renamed in the corresponding Wireshark files (usually located under the epan directory).

Hi,

Have a look at doc/README.plugins in the Wireshark source tree. At the end is 
some discussion how to port forward old style dissectors.

Thanx,
